$PECIFICATION forming part of Letters Patent No. 391,399, dated October 23, 1888.

Application filed February 20, 1888. Serial No. 264,693.

To all whom it may concern:

Be it known that I, WALTER MORTON BROWN, acitizeu of the United States, residing at Albany, in the county of Albany and State of New York, have invented a certain new and useful Improvement in Devices for Heating \Vater by Gas; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention consists of a water-motor, a fan, or other air-blast-producing device, awater-heatiug pipe or series of pipes,and forcedcombustion gas-burners in combination.

The object of my invention is to supply heated water for all purposes, but especially for domestic, culinary, and bathing purposes, by first making use of the pressure of the ca tor-supply to operate a water-motor, said water-motor being connected to and capable of operating a fan or other air-blast-producing device, the airblast thus produced being utilized by causing it to impinge upon or enter into the flame of the gas burning at the gas burners, thus producing a more intense heat, said gas-burners being so placed or arranged in relation to the watenheating pipe or pipes that the flame of the burning gas will impinge upon the water-heating-pipe, said water-heating pipes receiving the supply of water to be heated from the waste or discharge pipe of the water-motor. I accomplish this object by the combination of the various mechanisms illus trated in the accompanying drawings, wherein similar figures refer to similar parts through out the several views, and wherein Figure 1 shows a water-motor, a fan, a forced-combustion gas-burner and a waterheating pipe combined, so arranged that the water under pressure first enters the waterniotor, operates the same and the fan, and is then discharged into the water-heating pipe, where it is heated by the burning gas and discharged for use at the discharge-cock. Fig.

2 shows the same combination, but the water is first passed through the water-heating pipe, after which it passes through the water'niotor,

(No model.)

operating the same and the fan, and is then discharged from the waste-pipe of the motor for use, the operation being precisely the eX- act opposite of that shown in Fig. 1. Fig. 3 shows the water-heating pipe and gasbnrner in section, taken on line X X of Fig. 2, show ing the arrangement of the gas and air pipe whereby the air is enabled to reach and impinge upon the gas-flame or enter therein, causing the most intense heat possible to be obtained from burning gas.

In the drawings, 2 shows the water-motor; 3, the air-blast-producing device; 4,. the waterheatiug pipe; 5, the gas burners or perforations in the gas-pipe; 6, the air-pipe leading from the fan to the gas-burners; 7, a belt conneoting the drive-wheel of the water-motor and drive-wheel of the fan; 8, the main watersupply pipe; 9, the discharge or waste pipe from the water-motor in communication with the waterheating pipe; 10, the gas-supply pipe; 12,the discharge-coclgshowingthe heated water being discharged therefrom in Fig. 1, but not showing the water being discharged therefrom in Fig. 2; 13, the gas-pipe forming a part or portion of the burner; and 14:, the airtips leading from the air-pipe through the gaspipe.

The operation of this inventionis as follows: \Vater under pressure, as from city waterwork, pumps, or other devices, being allowed to flow into the water-motor causes the motor to operate at a speed proportionate to the pressure of the water in the supply-pipe, and the water-motor then operates the air-blastproducing device, creating a blast of air which flows through the air-pipe and impinges upon or enters the gas-flame, producing intense heat. The flame of the gas impinges upon the waterheating pipe and heats the water which is supplied to the water'heating pipe through the waste-pipe of the water-motor. The pressure of the water is therefore made to furnish an air-blast,with which intense heat is produced, by which the water is heated after or before it furnishes power to run the motor and fan,

in accordance with which form of combination, as shown in Figs. 1 and 2, is used.

The pipe 4 is the heating-pipe, which should be of larger capacity or diameter than its inlet and outlet pipes, so that the velocity of the flow of the water therein may be reduced as much as practical, and thus keep the water in pipe 4 for as long a period as practical, in order that it may take up all the heat possible.

I have shown in the drawings at Fig. 3 a form of forced combustion-gas burner, consisting of an air-pipe entered into a gas-pipe and having passage-ways for air under pressure to allow of the air entering or impinging upon the gasflame. I make no claim upon this form of burner, as it is not new, as will be seen by reference to the English patent to WVilliam Mather, No. 2,636, October 12, 1865, said patent having expired by due limitation of law, and the form of burner is therefore public property; nor do I make any claim in this application upon causing a gas-flame and airjet to converge upon a heatingpipe, a patent for such having been granted to me by the United States Patent Oliice January 31, 1388, No. 377,015.

If it is thought desirable,'a portion of the air may be taken from the air-pipe and caused to first mix with the gas before it is ignited by any well-known mechanism; but I preferably burn the gas without such admixture ofair,as with some gases such an admixture causes a tendency in the gas-flame to be easily extinguished.

I do not confine myself to the relative positions of the various parts of the combination shown in thedrawings. They may beset or arranged in any position desired; but I preferably set them as shown. The drive-wheel of the water-motor and the drive-wheel of the fan may be put in communication by any other means than by abelt,if desired. I preferably make use of a belt.

In order to havea perfect operation of this invention the discharge of the water from the waterunotor must not be held back or retarded, so as to produce a back-pressure in the motor.

I preferably make use of a fan, as shown, with which to produce the air-blast; but any air-blast-producing device may be used.

Having described my invention, so that any person skilled in the art to which it appertains may make and use the same, what I claim, and desire to obtain by Letters Patent, is

1. A water-motor having an inlet and outlet and a heating-pipe,and gasburners arranged adjacent to said heating-pipe for heating the latter, and an air-blast-producing device, said heating-pipe being attached to and in connection with the water-motor and capable of receiving the water discharged therefrom, and having a discharge-outlet for discharging the same, the ai r-blast-producing device being connected with the moving parts of the watermotor and capable of being operated thereby, said air-blast-producing device having an outlet-pipe for the discharge of the air-blast, said outlet-pipe having jet-apertures, the said jetapertures and the perforations in the gas burner being correspondingly located, so that the jets of gas and air from said jet air-apertures and said gas-perforations will unite and impinge upon the heating-pipe, substantially as described.

2. A water-motor having an outlet and inlet and a heating-pipe, and gas-burners arranged adjacent to said heating-pipe for heating the latter, and an air-blast-producing device, said heating-pipe being attached to and in connection with a water-supply and said motor and capable of discharging the water received from the water-supply into said motor, said motor having a discharge-opening for discharging the same, the air-blast-producing device being connected with the moving parts of said motor and capable of being operated thereby, said air-blastproducing device having an outletpipe for the air-blast, said outlet-pipe having jet-apertures, the said jet-apertures and the perforations in the gas-burners being correspondingly located, so that thejets of gas and air from said jet-apertures andsaid gas-perforations will unite and impinge upon the heating-pipe, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
